17th of May Norway Snapchat Story on May 17th, 2015

I know the title is a little redundant but it is what it is. The 17th of May is when Norway celebrates its Independence Day much like the United States celebrates July 4th. The Snapchat Story will teach you much more about Norway then you likely ever knew. If you are from Norway, please tell us more about the 17th of May. What do you do? What is your favorite part of the day? Here are some of the screenshots I took of the Snapchat Story:

I know very little about this particular holiday but I would love to learn more. Please comment with what you know and have experienced during this holiday.
